python - Template doesn't exist on heroku, but does locally -

so tested project locally, , seems work perfectly.

although, when pushed project heroku server, except 1 link didn't seem work. when requesting page, got templatedoesnotexist @ /locations/add/ error. once again, page works locally, how can page doesn't exist?

here urls.py snippet:

    urlpatterns = patterns(         '',          url(r'^add/$', login_required(addlocation.as_view()), name="add_location"), ) 

the view:

class addlocation(view):      template_name = "dash/addlocation.html"     form = locationform()     def get(self, request, *args, **kwargs):         user = user.objects.get(username=request.user.username)         self.form.fields['existing_regions'].queryset = region.objects.filter(location__manager=user)         return render(request, self.template_name, {'form': self.form}) 

and full traceback:

here template dirs:

template_dirs = (     # put strings here, "/home/html/django_templates" or "c:/www/django/templates".     # use forward slashes, on windows.     # don't forget use absolute paths, not relative paths.     os.path.join(base_dir, '../templates'), ) 

and here installed apps requested:

installed_apps = (     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.sites',     'django.contrib.messages',     'django.contrib.staticfiles',     'django.contrib.formtools',     #'rest_framework',     # uncomment next line enable admin:     'django.contrib.admin',     # uncomment next line enable admin documentation:     'django.contrib.admindocs',     #'pinpoint.apps.careers',     #'pinpoint.apps.contact',     'pinpoint.profile',     'south',     'pinpoint.apps.beaconmanager',     'pinpoint.apps.api',     'pinpoint.apps.geofencemanager',     'pinpoint.apps.locationmanager',     'pinpoint.apps.messagemanager',     'django_extensions',    ) 

my template loaders:

template_loaders = (     'django.template.loaders.filesystem.loader',     'django.template.loaders.app_directories.loader', #     'django.template.loaders.eggs.loader', ) 

i can provide more details if needed. know why link doesn't exist on heroku locally?

okay have realized wrong.

two things:

1. the urls.py app needed django.core.urlresolvers import reverse
2. the template_name = "dash/addlocation.html" needed changed template_name = "dash/addlocation.html"

thanks pointed me in right direction.
